Sap.Data.Hana.HanaException: 'Parameter/Column (4) not bound.'

See original GitHub issue

I’ve using linq2db for SapHana and when I’ve updated to linq2db version 2.x there is an issue with an query. When I revert to linq2db version 1.10.2, my query works again.

Exception message: 'Parameter/Column (3) not bound.'

Steps to reproduce

Execute the query.

using (var db = new SboDataConnection(connectionString, ProviderName.SapHana))
{
    var query =
        db.OITM.Where(x =>
                (x.validFor.Equals("Y") && (x.validFrom == null || x.validFrom <= dateTime) && (x.validTo == null || x.validTo >= date)) ||
                (x.frozenFor.Equals("Y") && (x.frozenFrom == null || x.frozenFrom <= dateTime) && (x.frozenTo == null || x.frozenTo >= date)) ||
                (x.frozenFor.Equals("N") && x.validFor.Equals("N"))
            ).Select(x => new
            {
                Code = x.ItemCode,
                Name = x.ItemName
            });
    query.ToList();
}
